Burn in period

@rifraf4u @jetter 

Rifraf, its cool if you believe its marketing hype. Whats kind of funny is I was once in your camp. Whether its because I was once a cable denier or whether its because I upgraded my components over time and the system became more resolving or it may be that I finally happened upon the proper wire/system synergies or any number of other explanations....doesnt really matter to me. I have experienced it and its real. I have, however, avoided these kinds of threads because there is literally nothing that can be communicated to you that would convince you to even have an open mind and to try it for yourself. If it makes no difference in your system then so be it. People do get wound up though when they are certain something cant possibly be true...

Jetter, to me, having a cable cooker may be the only true way to determine differences, given our aural memory and how unreliable it is. To those out there who are certain breakin isnt real, a cable cooker provides an opportunity for a pretty quick A/B test. Cable companies should have a loaner program or when someone buys a new set of cables, send two pair of identical serialized cables. One cooked, one not. You will hear the difference.

As I stated earlier, I dont have a vested interest in anyone believing in breakin. Couldnt care less. But just because rifraf or others havent experienced it for themselves doesnt mean it isnt real.

@ghasley, you could take objective measurements using REW or similar and post them here. Before and after. That would then be more like a science instead of subjective bias. 

@ghasley , but in the end it doesn't really matter - does it... if you have gained additional joy/pleasure through your investment in cables, subjective or objective, you did gain said joy. 

LOL...so what do you suggest be measured? Additionally, isnt it up to you to prove scientifically that the effect that if it measures the same but sounds different cant be? If you are convinced cables don't make a difference, that differences in electronics cant be heard when they "measure" the same and that breakin cant be real, why not return to ASR?

things that get hot, especially things that glow, will change with use, thus burn in. Materials do not change appreciably at room temperature or with the relatively tiny currents put through them by generating music.

If a manufacturer is designing components (other than tubes) in a power supply, amplifier circuit , or especially a low power component such as a DAC to get hot, then that component is probably not for me. I guess some amplifiers might sometimes be an exception here (high currents) but preferably not.

Copper is not directional. To make a wire directional you have to add electronic components.  If a cable is shielded and grounded only on one end (a good way to avoid ground loops), it might be better to ground on the source end...but if both components are grounded to the same circuit, it really shouldn't matter.

Saying that a component needs "burn in" is a way of saying "listen to it a while before you return it" that sounds like it has a reason behind it.
